WINTEMP Under-Sink Instant Hot Water Dispenser, 750/1300W Dual Power

The WINTEMP Under-Sink Instant Hot Water Dispenser provides quick hot water directly at the kitchen sink, reducing the wait for kettles or stovetops. Designed for households that regularly prepare warm beverages, oatmeal, or quick meals, it pairs a dedicated under-sink tank with a dual-spout faucet. If you want on-demand heated water without sacrificing countertop space, an under-sink system provides a practical and integrated solution.

A notable feature is the dual heating control, allowing users to toggle between 750W and 1300W power settings. At 1300W, cold water reaches temperature in approximately 8 minutes, while 750W heats the tank in about 10 minutes. Subsequent heating cycles require only 3 to 5 minutes. The 0.66-gallon food-grade 304 stainless steel tank outputs 0.634 gallons (2.4 liters) per minute, delivering up to 9.6 standard 250-milliliter cups per minute for food prep and hot drinks.

The faucet is made from 304 stainless steel with a brushed finish and delivers hot and filtered cold water through separate outlets at the same time. Under the counter, the dispenser measures 8.62 by 7.05 by 10.79 inches, roughly matching the profile of a 1-gallon water container. This compact size preserves under-sink cabinet capacity for household storage.

There are a few operational considerations to note. The unit requires an accessible power source beneath the sink, and initial warm-up requires an 8 to 10 minute wait depending on the wattage chosen. Furthermore, although the faucet supports filtered water, the listing does not state whether a water filter is included in the box, nor does it list specific temperature controls beyond the two wattage modes.

Verdict: The WINTEMP Under-Sink Instant Hot Water Dispenser is a great fit for busy kitchens needing fast hot water for cooking and drinks. Its dual wattage options, stainless steel build, and compact under-counter footprint make it a capable addition to any sink setup.

A great fit if you:

• Frequently prepare oatmeal, instant noodles, or hot drinks and want immediate water directly from the kitchen sink.
• Need the ability to choose between 750W and 1300W power levels to fit your home electrical preferences.
• Want a single faucet that dispenses heated water and filtered drinking water at the exact same time.
• Have limited room under your sink and need a compact tank that takes up minimal cabinet storage.

Consider something else if you:

• Require specific digital temperature controls that let you set precise water degrees, which this listing does not specify.
• Lack an electrical outlet under your sink to connect the 750W or 1300W power system.

Confirm on the listing:

• Measure your cabinet space to confirm the 8.62 by 7.05 by 10.79 inch dispenser tank clears your existing sink plumbing.
• Check whether your sink or countertop already features an available mounting hole for the dual hot and cold faucet.
• Confirm that an electrical outlet is available under your counter to connect the dispenser.
• Check if a water filtration cartridge is included or sold separately, as the faucet supports filtered water but filters are not detailed.

How to compare your options: When shopping for under-sink water heaters, evaluate tank capacity, heating speed, and tap design. This dispenser provides a 0.66-gallon food-grade stainless tank and dual wattage options that let you prioritize either lower energy draw or faster heating. Compare these specs against your household hot water volume and available cabinet dimensions.

• Follow the included step-by-step manual carefully when attaching the water line, dual faucet, and electrical connections to ensure a secure setup.
• Choose the 1300W power mode when you want faster 8-minute initial heating, or switch to 750W if you want to operate with a lower wattage draw.
• Allow 3 to 5 minutes between large dispensing cycles so the 0.66-gallon stainless tank can fully reheat for your next use.
• Wipe the brushed stainless steel faucet with a damp cloth and mild dish soap to keep the finish clean without causing surface scratches.
• Ensure the under-sink area around the unit remains clear of obstruction so you can inspect connections and power cords whenever needed.
